The Difference Between 265/75R16 and 265/70R16 Tires: A Comprehensive Guide

265/75R16 is a wider tire than 265/70R16.

Difference Between 265/75R16 And 265/70R16

The primary difference between a 265/75R16 and 265/70R16 tire is their sidewall height. With the 75R16 tire, the sidewall height is 75% of the tire’s section width (265 mm), while with the 70R16 tire, its only 70%. The taller 75R16 tire will give your vehicle a more aggressive look while providing increased ground clearance and better off-roading capabilities. On the other hand, the shorter 70R16 tires will increase high-speed stability and on-road handling capability. Additionally, remember that when you select tires of different sizes or configurations you will also need to adjust your wheel size accordingly.

Tire Size – Compatibility

The primary difference between the 265/75R16 and 265/70R16 tire size is the sidewall height. The sidewall height of the 265/75R16 tire is 8.5 inches while the sidewall height of the 265/70R16 tire is 7.5 inches. This difference in sidewall height affects the overall diameter of each tire size. The overall diameter of the 265/75R16 tire is 33.1 inches, while the overall diameter of the 265/70R16 tire is 32.4 inches.

The difference in overall diameter means that these two tires are not interchangeable, and are not compatible with each other when replacing tires for a vehicle. It is important to note that when selecting a replacement tire, one must select a tire with an identical size to ensure proper fitment and performance on their vehicle.

Load Capacity

The load capacity of both tires can be found in their respective Load Index ratings on their sidewalls which correlate to specific load values which are stated in kilograms or pounds depending on region and market. The load index rating for the 265/75R16 tire is 121, which corresponds to a load capacity of 2,039 lbs or 925 kgs, while the load index rating for the 265/70R16 is 120 corresponding to a load capacity of 2,000 lbs or 907 kgs.

Speed Rating

The speed rating indicates at what maximum speed a given tire can safely handle when loaded with its maximum recommended load capacity. The speed rating for both tires is Q indicating that they can safely handle up to 99 mph (160 km/h) when loaded with their respective maximum recommended loads capacities as previously mentioned above.

Fuel Efficiency

Fuel efficiency ratings differ between various types of tires but generally speaking, all-terrain tires tend to have lower fuel efficiency ratings than more specialized road-oriented tires such as touring or high performance tires due to increased rolling resistance caused by larger tread blocks and deeper tread depths common among all-terrain tires. Both the 265/75R16 and 265/70R16 are all-terrain tires so there will likely be no noticeable difference in fuel efficiency between these two sizes when fitted on a vehicle due to similar rolling resistance characteristics between them.

Tire Construction Variance

When comparing 265/75R16 tires to 265/70R16 tires, there is a difference in the construction of the tire. The construction of a tire is how a tire is designed and constructed to provide grip, traction, and durability. The 265/75R16 tire has a more aggressive tread pattern compared to the 265/70R16 tire. This means that the 265/75R16 will provide more grip and traction in off-road conditions such as mud, snow, and rocks. The 265/70R16 will provide less grip and traction in these conditions as it is designed for more highway use. Additionally, the 265/75R16 has a thicker sidewall which provides improved handling and stability when driving at higher speeds.

Cost Variance

When comparing the cost of 265/75R16 tires to that of 265/70R16 tires, there is typically a slight difference in price. The cost of a set of four 265/75R16 tires can range anywhere from $500-$700 depending on brand and model whereas the cost of four 265/70R16 tires can range from $400-$600. This price difference reflects the differences between the two sizes regarding construction and performance capabilities.


The brand or type of tire you choose will ultimately determine how well your vehicle performs when using either size tire. There are numerous brands available for both sizes including Michelin, Bridgestone, Goodyear, Firestone, Yokohama, Dunlop, Continental and many more. Each brand offers their own unique performance capabilities so be sure to do your research before deciding which size and brand best suits your needs.

Treadwear Warranty

The treadwear warranty offered on each size tire varies depending on brand and model. Most major brands offer up to 80,000 miles on their tires but some brands may offer up to 90,000 miles depending on their specific model or type of tire chosen. Its important to read the fine print before purchasing any set of tires as some warranties may have certain restrictions or requirements that must be met in order for them to be valid..

FAQ & Answers

Q: What is the difference between 265/75R16 and 265/70R16 tire sizes?
A: The primary difference between these two tire sizes is that the 265/75R16 tire has a larger overall diameter than the 265/70R16 tire, which results in a taller sidewall height. The 265/75R16 also has a higher load capacity than the 265/70R16, but both tires have the same speed rating.

Q: What type of construction does each of these tires have?
A: Both the 265/75R16 and 265/70R16 utilize radial construction, which features belts of steel or Kevlar and layers of polyester cord to provide strength and flexibility.

Q: Is there a cost variance between these two tires?
A: Yes, typically the 265/75R16 will cost more than the 265/70R16 due to its higher load capacity and greater overall diameter.

Q: Are these tires compatible with all vehicles?
A: Generally, both the 265/75R16 and 265/70R16 are compatible with most vehicles, but it is important to consult your vehicle’s manufacturer guidelines to ensure compatibility.

Q: What type of treadwear warranty comes with each tire?
A: This depends on the individual manufacturer, but most brands offer similar treadwear warranties for both the 265/75R16 and the265/70R16. It is always best to consult with your tire supplier for more specific information on warranty options.
